A lot of research will yet have to be conducted
High-tech greenhouse operations would likely utilize plants planted in soil, exposed to sunlight, with double or triple the current CO2 density in the air, potentially enhanced with artificial sunlight during the dark hours. A lot of research will yet have to be conducted, in order to explore the most efficient lighting, nourishment, and atmosphere, to maximise plant growth. When all is optimized, a 10 to 12-fold production yield might be achievable, with potentially 6 harvests per year.
